Materials Data on CsAgC2 by Materials Project
CsAgC2 crystallizes in the tetragonal P4_2/mmc space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a distorted body-centered cubic geometry to eight C1- atoms. All Cs–C bond lengths are 3.54 Å. In the second Cs1+ site, Cs1+ is bonded in a distorted body-centered cubic geometry to eight C1- atoms. All Cs–C bond lengths are 3.54 Å. There are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a linear geometry to two C1- atoms. Both Ag–C bond lengths are 2.04 Å. In the second Ag1+ site, Ag1+ is bonded in a linear geometry to two C1- atoms. Both Ag–C bond lengths are 2.04 Å. There are four inequivalent C1- sites. In the first C1- site, C1- is bonded in a distorted linear geometry to four Cs1+, one Ag1+, and one C1- atom. The C–C bond length is 1.25 Å. In the second C1- site, C1- is bonded in a distorted linear geometry to four Cs1+, one Ag1+, and one C1- atom. The C–C bond length is 1.25 Å. In the third C1- site, C1- is bonded in a distorted linear geometry to four Cs1+, one Ag1+, and one C1- atom. In the fourth C1- site, C1- is bonded in a distorted linear geometry to four Cs1+, one Ag1+, and one C1- atom.
